Never has there lived a man privileged, like Solomon, to make the demons amenable to his will. God endowed him with the ability to turn the vicious power of demons into a power working to the advantage of men. He invented formulas of incantation by which diseases were alleviated, and others by which demons were exorcised so that they were banished forever. As his personal attendants he had spirits and demons whom he could send hither and thither on the instant. He could grow tropical plants in Palestine, because his ministering spirits secured water for him from India.
